1) Pilot will not light, and Piezo Igniter does

not produce a heavy blue spark.

a. Electrode wire (at Piezo Igniter) not

pushed completely on.

b.  Piezo igniter is defective

•

  Make sure connections are solid.

•

  Replace piezo igniter.

2) Pilot will not light, but Piezo Igniter pro-

duces a heavy blue spark.

a. Incorrect lighting procedure.
b. No gas to appliance due to shut valves or

disconnected gas lines.

•

  Carefully follow the lighting / operating

instructions found in the appliance of this
owner's manual.

•

  Check for multiple gas shut-offs; check

gas supply lines.

3) Pilot will not stay lit.

a. Thermocouple is not firmly connected to

control valve.

b. Pilot flame is not directed to top of ther-

mocouple.

c. Thermocouple is defective. Make sure

connection is solid.

•

  Ensure thermocouple is fully inserted into

pilot assembly.

•

 Replace 

thermocouple.

4) Pilot flame stays lit, but main burner will

not light.

a. Burner control switch (on control panel) is

in "OFF" position; or thermostat (if in-
stalled) is turned off or temperature set-
ting is too low.

b. Electrical wiring is damaged or poorly

connected

c. One of the following components may be

defective: burner control switch, thermo-
stat, vent spill switch, or thermopile.

•

 Position the burner control switch to

"ON"; or adjust the thermostat. Refer to
manufacturer's instructions for thermo-
stat.

•

  Refer to Control and Safety Wiring Dia-

gram (page 18) and check electrical
connections.

•

  Refer to Control and Safety Systems

Wiring Diagram (page 18). Electrically
bypass components one at a time and
replace defective item.

5) Main burner stays lit for up to 10 minutes

and then shuts off, pilot flame remains lit.

a. Vent is blocked; flue gas is "spilling",

which activates the spill switch and shuts
down the appliance.

b.  The house is negatively pressurized re-

sulting in spill switch activation.

•

  Examine venting system for blockage.

Remove any blockage.

•

  Open a window to see if the problem is

corrected.

6) Smell of gas

a. Loose fittings may be allowing gas to leak

out.

•

  Check all joints for leakage: pilot assem-

bly, gas supply system, main burner as-
sembly, pilot and burner adjustment
screws. Use a proper leak check solu-
tion. WARNING: Never use an open
flame to check for leaks.

7) A thin coating of black soot forms on the

window. NOTE: See page 16, Cleaning
Glass.

a.  Burner primary air inlet is restricted or

blocked.

b.  Flames make contact with logs or other

surfaces.

c. Improper 

venting.

•

  Be sure all openings (fresh air inlets) in

stove are free from dust and debris.  Re-
check these areas periodically.

•

  Make sure ceramic logs are in their cor-

rect positions.

•

  Check for flue blockage, disconnected

flue, improper installation.  Make appro-
priate corrections.

8) A white coating forms on windows, logs,

and / or inside walls of firebox.

a. Residues / impurities being burned off.

•

  Follow cleaning guidelines outlined in the

MAINTENANCE section of this manual.

9) Circulation blower makes a humming

sound, but there is no circulation air.

a. Impeller blades in circulation blower are

dirty.

b. Circulation blower is defective.

•

  Disconnect electrical power to circulation

blower, access blower and clean impeller
blades as outlined in the MAINTE-
NANCE section of this manual.

•

 Replace 

blower.

♦

  Thermopile: Millivolt production should be a minimum of

325 MV with pilot only.

♦

  Thermocouple: Millivolt production should be a minimum of

14 MV with pilot only.

♦

  TP 50-60 MV

♦

  TP 1 1/2-2 Min. (3 max.) if longer, replace thermopile.
